A balance transfer offer can feel like a lifeline when your card interest is eating your salary. Move the debt to a lower rate, pay it down faster, done. But a few common slip-ups can turn a good deal into an expensive one.
Short answer: A credit card balance transfer usually carries a processing fee plus 18% GST, and the low rate lasts only for a set period before the balance moves to the card’s normal rate. You save money only if you account for the fees, clear most or all of the balance before the offer ends, and stop adding new debt to the old card.
How a balance transfer is priced
A balance transfer moves what you owe on one card to another card or lender, usually at a lower promotional rate for a fixed number of months. You typically pay:
- A processing or transfer fee, often a percentage of the amount moved, plus 18% GST.
- Interest at the promotional rate, plus GST on that interest.
- The card’s standard rate after the promo ends, on whatever balance is left. Revolving card interest in India is typically around 3–3.75% a month.
Here is an example we will use throughout. The numbers are illustrative; real offers vary.
Meera, 32, Chennai, owes ₹1,50,000 on a card charging 3.5% a month. A balance transfer offer charges a 2% fee (₹3,000 + ₹540 GST = ₹3,540), 1% a month for 6 months, and then 3.5% a month on any remaining balance.
| Plan | Monthly payment | Months to clear | Interest + GST + fee |
|---|---|---|---|
| Stay on the old card | ₹15,000 | 14 | about ₹47,496 |
| Transfer, pay ₹15,000 a month | ₹15,000 | 12 | about ₹20,716 |
| Transfer, pay about ₹27,000 a month | about ₹27,000 | 6 | about ₹9,623 |
The transfer helps in both cases. But the gap between the second and third rows, about ₹11,000, is the price of the mistakes below. You can try your own numbers in our balance transfer calculator.
Seven mistakes that cost you money
1. Ignoring the fee and GST
A “1% a month” headline sounds cheap, but the ₹3,540 fee is paid on day one whether you clear the balance in six months or not. On a small balance or a short promo, the fee can cancel most of the saving. Always add the fee plus GST to the interest before comparing offers.
2. Missing the promo end date
When Meera pays ₹15,000 a month, she still owes about ₹68,241 when the 6 months end. That balance then moves to 3.5% a month, and she pays about ₹8,935 more in interest and GST over the next six months. That is more than she paid during the entire promo period (about ₹8,241).
Divide the transferred amount by the number of promo months before you apply. If you cannot pay roughly that much each month, plan for what happens to the leftover balance. For Meera, about ₹27,000 a month clears it in time.
3. Using the old card again
This is the costliest mistake. Once the old card shows a zero balance, the full limit is available again. Spend on it and you have the transferred balance plus fresh debt, often at the old card’s full rate. If you then fail to pay that card in full, interest usually applies to new purchases too.
Remove the old card from shopping apps and wallets, and keep it at home until the transferred balance is cleared.
4. Transferring more than you can clear
A bigger transfer means a bigger fee and a bigger balance left when the promo ends. Move only what you can realistically repay within the promo period, or close to it. If the total is too large for that, a fixed-tenure personal loan may suit better. Our comparison of balance transfer vs personal loan works through both with fees.
5. Missing a payment
A missed payment brings late charges if it is overdue more than 3 days after the due date, and it is reported to the credit bureaus. Some offers also end the promotional rate if you miss a payment, so check the terms. Set up autopay for at least the minimum amount due, then pay extra manually.
6. Applying for too many offers at once
Each card or loan application is a hard enquiry on your credit report, which can dip your score slightly. Several in a short span can make lenders wary. Compare offers first, check eligibility where you can, and apply where you are likely to qualify. Checking your own score is a soft enquiry and does not affect it.
7. Closing or keeping old cards without thinking
Closing the old card removes temptation but also reduces your total available limit, which can push up your credit utilisation. Keeping it open helps utilisation but only if you do not use it. A middle path many people use is to keep the card with no balance and lower its limit, or keep it locked through the bank’s app. Decide based on how much you trust your own habits, not just your score.

Check before you apply
- The APR and total amount payable in the Key Fact Statement (KFS), compared with what you pay today
- Processing fee plus 18% GST, and any insurance or add-ons (ask whether they are optional)
- Foreclosure charges on your existing loans and on the new loan
- That the new loan covers every debt you plan to close, and that you will get a closure letter or NOC for each
- Whether the new EMI fits your monthly budget after essentials and savings
- That the lender is RBI-regulated: check our lender directory and loan app directory
Frequently asked questions
What are the charges for a credit card balance transfer?
Usually a processing fee, often a percentage of the amount transferred, plus 18% GST on it. You also pay interest at the promotional rate, with GST, and the standard card rate on any balance left after the promo ends. Check the full terms before you accept.
Is a balance transfer worth it for ₹1.5 lakh of card debt?
In our example it saved between about ₹27,000 and ₹38,000 compared with staying on the old card. The saving depends on the fee, the promo rate and length, and how fast you repay. Run your own numbers before deciding.
Does a balance transfer affect my CIBIL score?
The application creates a hard enquiry, which can cause a small dip. Paying on time and bringing your total balance down usually helps over the following months. Missed payments or new debt on the old card would hurt.
What happens when the promotional period ends?
Any balance still outstanding usually moves to the card’s standard rate, which is typically around 3–3.75% a month. That is why clearing most of the balance before the end date matters.
